Solidium MDF And Machined Components

A Superior Choice For Consistency And Value

Solidium LITE Mouldings


Designed for long run efficiency, Solidium LITE can help reduce product weight and production waste ... more

Solidium is the cornerstone of the MDF product line from Del-Tin Fiber and is ideal for table tops, contoured door panels and drawer fronts as well as other profiled components requiring precision part manufacturing. Highly refined fibers and a consistent core provide excellent machinability and clean, sharp edges for cutting and drilling applications. Solidium also delivers all the surface characteristics for outstanding finishing results. Smooth and even surfaces provide an excellent substrate for painting, printing or the application of veneers and laminates while machined edges accept edge-banding reliably. Solidium consistently delivers a solid performance from start to finish.
